Opus tessellatum

Opus tessellatum is a Roman technique used to create large decorative mosaics on floors and walls. It involves arranging small, uniformly shaped stone or glass tiles called tesserae into geometric patterns or images. These tiles are often made from durable materials like colored stones or glass, ensuring the mosaic withstands foot traffic and time. The technique allowed for detailed and vibrant designs, showcasing artistry and craftsmanship. Opus tessellatum was common in Roman architecture, especially in public buildings and wealthy homes, serving both decorative and functional purposes.
